Cosmarium ungerianum (Nägeli) de Bary
Reference: Nägeli 1849
Synonym: Euastrum ungerianum Nägeli
Compare with: Cosmarium triplicatum
Remarks: West & West 1897b have described a var. subtriplicatum that differs from the nominate variety only by a more rectangular outline like the specimen below. It is questionable whether this justifies a separate variety.
